Focus zoom on Root

[rfzsal]

Is there a way to focus the zoom on the root instead of zoom to fit?

I want something like this by default.

here is my current code

const renderChart = (data) => {
        const options = {
            width: "100%",
            height: 700,
            nodeWidth: 120,
            nodeHeight: 80,
            childrenSpacing: 100,
            siblingSpacing: 30,
            direction: "left",
            enableToolbar: true,
        };

        const tree = new ApexTree(document.getElementById("svg-tree"), options);
        tree.render(data);
};

Thanks
